Controlling the Diurnal Lights (6012) and Optional Fluorescent Lights (LGHT303)
The diurnal chamber comes with a fluorescent lighting system used to simulate day and
night testing. This option is also available on the model 6010 & 6015 as LGHT303.
There are separate temperature and humidity (optional) set-points that correspond with
the lights on (day) and lights off (night). The set-points can also be made the same if
continuous conditions are needed throughout the light cycles.
The diurnal lighting system consists of two separate light banks. Each light bank has
two lamps and is mounted on the underside of a shelf. The banks can be located on the
same or separate shelves. Each light bank has a corresponding switch that enables
that light bank to come on when the timer is on. Only the light banks that have their
individual switch turned on will illuminate. The green indicator light above the light bank
switch signifies when each light bank is on.
For units equipped with ramping controllers (DLUX301 & DLUX302), the timer can be
used to trigger an event in a profile to switch between two set-points (if programmed
accordingly).
